Strap for Constellation Quartz 24 Brushed Stainless Steel / MOP

The lug width of the Constellation 123.10.24.60.05.001 is exactly 18mm. This measurement refers to the linear distance between the inner edges of the metal lugs of the case. It is essential to respect this precise dimension when purchasing an aftermarket strap, as the spring bar must fit perfectly into the male terminals to ensure comfort and security in use.

For the Constellation 123.10.24.60.05.001, alligator represents the most elegant choice thanks to its regular texture that enhances the geometry of the claws. However, vegetable-tanned calf leather offers versatility and a patina that evolves naturally over time, creating a personal relationship with the watch. For daily use, an FKM rubber or NATO strap maintains the delicate proportions of the case without weighing it down, while shell cordovan represents the premium option for collectors seeking superior tactile characteristics.

The strap is changed by means of the metal spring bars integrated into the case. To remove the current strap, gently push inward the elastic pin that fastens the strap to the male terminals, using a small flat tool (such as a spring bar tool). Once one lug is freed, extract the old strap. To install the new one, align the strap lugs with the terminal holes on the case, then reinsert the elastic pin. We recommend performing this operation with care to avoid scratching the steel case.

Yes, all straps designed for the 18mm lug width are compatible with the Constellation. It is essential to verify this specific dimension before purchase. On milanostraps.it you can find 18mm straps ready for shipment in multiple materials – alligator, calf, shell cordovan, rubber – customizable in sizes, initials and stitching thread color. The Casati Milano atelier also offers the possibility of made-to-measure straps with personal consultation of the leathers.

The lifespan depends on the material chosen and the intensity of use. A quality alligator strap, with ordinary maintenance (regular cleaning and annual water-resistant treatment), maintains structural integrity for 5-7 years of daily use. Vegetable-tanned calf leather shows similar durability, but the patina it develops makes it more appreciated over time. Shell cordovan, given the fiber density, can last 10+ years if cared for. At the end of its useful life, you can contact Casati Milano to regenerate the strap, significantly extending its use.
